Command Script Editing

Hi,
I was just wondering if there was anyway when someone in my session types: /911[Nothing Else] it wouldn’t show in chat and it gives them this feedback: [911] Error incorrect value, try using this format: /911 [Location],[Incident],[Possible Description]

Thanks for any help!

they need to use that format /911 grove street shooting purple jacket and slacks if they don’t use the whole format it wont go through as a command

I know that’s what I want, but because of the creator of this script people can put whatever they like and they can just leave it blank
